About the book: 2023 / If you are the first beauty among your colleagues, then never argue with an inconspicuous gray mouse. If you are a successful businessman, then do not let your friend drag you into a dubious competition. Well, if you are a gray mouse and have long ago exchanged your personal life for work, then having received a chance to relax at the expense of suddenly generous management, do not flatter yourself. There’s definitely something behind this and it wouldn’t hurt to understand what it is before trouble comes. Remember, free cheese is only in a mousetrap, and for everything else you have to pay.
